and useful Improvements in Convertible Chairs, of which the followingisa specifieation.

My invention relates to convertible cha-irs, and more particularly tothat class of the saine in which the frames are foldable. i

One of the objects of my invention is to provide a chair which may beconverted into a' cot or bed.

Another object is to provide a chair which may be converted into adouble chair.

' Anothcrobjeet is to combine a table and convertible chair so thatthetable will act as a support when the device is converted into a double c'liair or bed.

Another object is to provide a convertible chair having a scat sectionadapted to act as va support when the device is converted into a bed,anda further object is to construct a chair having vthe framev sectionsadapted to confine a mattress, bedding or other body material. v

With these and other objects in view my invention consists in thedetails of construction and manner of operation more fully described inthe following description and accompanying drawings in which likereferencev characters refer to corresponding parts.

-In the drawings: Figure 1 isa side elevation of my device showing onearm of the chair detached and the forward portion of the mattress brokenaway Fig. 2 a front i elevation thereof showing a portion of one armbrokenaway; Fig. 3 a side elevation showing the chair converted into adouble chair, the portion in dotted lines showing a further conversioninto a' bed; and Fig. 4, a, lan view of the device converted into a.bed,

theinattress and U shaped section being removed.

My device generally comprises a base A, .a foldable back B, springs C,table E and stool F. The base A is made up of a rectangular skeletonframe 1, 1 12 supported by suitablel legs 2, 2vand 2', 2 on each'sidethereof respectively. vertically swinging members 3, 3 have their lowerextremities pivoted at 4, 4 to the sides and at the rear of the base.The vertical members 3, 3 project slightly forwardly as theyapproachtheir upper extremities which latter are pivoted at 5, 5 to therearwardly projecting upper extremities of the', vertically swingingmembers 6, 6. Projecting forwardly from the lower ex- ,tremities of themembers 6, 6 at some distance above and parallel to the base are themembers 7, 7 which hitter have their forward extremities pivoted to thecorresponding extremities of the vertically swinging U shaped sectionhaving a middle portion 9 and side legs 9, 9', by means of the pins Sand the corresponding Vbayonet slots 8.

All of the frame members above described may be made from t. shaped barsbent to the required configuration and vpresenting their transverse andlongitudinal webs (1, (1 and t), t/ on the exposed sides of the chair.The'transverse webs a, c of the members 1,1/ of the seat frame and ofthe members I, 3 and 6, 6 of the back may ybe. perforated at intervalsto enable springs (il to be strung from the wens c on the one side tocorresponding webs (1. .on the other side of the frame, thus forming alower seat section and forward and rear back sections, the springs be-`ing strung longitudinally between the forward. member 12 of the seatframe and the tie rod 10 which latter is drawn transversely through theoppositely disposed longitiulinal webs b, b at the lower ends ofthemembei' 6, 6. The transverse webs (1.,afk Yare. cut

ties of thc members 3,3 and 6, 6 in order not to interfere with theswinging movement of these members. ',lhe upper extremities of themembers 3, 3 and 6, 6 project sulliciently foiwardlyand rearwardly tospace theforward and rear back sections a predetermined distance apartto accommodate a suitably folded mattress, bedding or other body betweenthem.

lf desired ornamental fabric or-otliei' material may be sewed ortl'irown loosely over the. exposed sides of the springs, blut this isnot material since the folded mattress embraced bctween the tightlystrung springs forni avery desirable cushionv or upholstering forthe'back and seat. tress at thetop of the back tends to compress thesame at this4 point and to lspread the "folded sections at the lowereXtreinity'ttiei-eof, thus thc mattress taken toggtp forward swingingsection betwcen the bars G, 6 form a yielding back.` 'Vlie pivoted Ushaped section formed by the members S), 9', 9, may also yield upwardlyand downwardl with the mattress to accommodate the swing- 'er with tl Byfolding the i'natingmovement of'forwardly projecting menibers 7,7.Pivoted at thelr lower ends on the transverse webs of the seat frame 1,1, 12 are the sidearms 11, 11 bent at an angle and .having theirltransverse webs cut away as they ap roach their respective .ends to'accomlnodfate the back, their longitudinal web 3 being notched at 13near their rearward extremities to enable the same to be sprung over thepinsl/i, 14 mounted on ,the members 3i, 3 to support the latter in anupright position. A'table E having a drawer in each end thereof isbolted to the rear of the webs a, a

of-the vertical members 3, 3', and a stoolF v15 -is movably'4 secured tothe chair frame by' a suitabliklink 15.'. When the stool is not in seit`may .be secured beneath t'he tableto thecross bar 16 by a hook 17. Whenit is desired to convert the chair into a double chair as shown in'Fig.3 the side "arms 11,-11 are sprung upwardly to enableV the notches toclear the pins 14, 14. which1 causes the-back members 3, 3 to bereleased and swung downwardly and rearwardly on their pivots 4, 4 to ahorizontal position in i whichv position thetable E acts asa support andthe U shaped section is' detached from the members '7, 7 and 'isreplaced so that its vvmiddle, bar 9 rests on the free extremities Aofthe members 7, 7 being held in place by means of thepins 8, 8 resting inthe bayonet slots 82 and 83 respectively thus -forming a cross armvbetween the two seats.- The sidearms 11, 11 may then be turned on theirpivots 12,112 towards each other and are suitably secured together by apin 18 in one arm passing into an aperture notsh'own in the other arm,both arms thus secured acting as an end arm for the chair.

sired, however the arms 11, `11,may remain inthel position shown inFigs. 1 and 2 the notches 13 being sprung over .the pins 8.

jThe chair may be further converted into a bed -by unfolding the backmembers 6, 6 rearwardly, the members 7, 7 acting as legs or props asshown in dottedl lines in Fig. 4.'

Themattress Dmay be so folded within the cha-ir so asl to unfold withthe frame members l when the device is converted into a bed, and

the stool .F hooked'to the cross bars 16 may be sus ended out of contactwith the Hoor beneat the bed. The side arms 1-1, 11 ar-v ranged as inFigs. 3 and 4 act as ahead to the bed.` i

When the device is' not intended to be con.- verted into a double or twoseated chair the U 'shaped section may bey dispensedwith, if-

desired, as shown lin Fig. 4.

' Having now described my invention what' 'I desire to claim and protectby Letters Pat'-1 ent'isz.

1. A convertible chair comprising a base and a back having its lowerextremities pivoted to said base and arrangedlto swing rearwardly 'intoa horizontal position to form an an additional seat and horizontallyswinging side arms mounted on said base arranged to support said backin' an-upright position and ltoo swing inwardly to .form an armfor'said` ase.

3. A convertiblev chair comprising a base, a back having front vandrea-r sections pivotally connected at their upper extremities and spacedapart 'to confine bedding, the rear section having its lower extremitypivoted to said base and the. front section having a forwardlyprojecting support rigidlyconnected to its ower extremity and spacedabove said base also to confine bedding, the? said .back bein arrangedto swing 'rearwardly and to be unfo ded to form a bed. and the said suort being arranged to act as a'prop for saidjh 4. In a convertiblechair, a base, a rearwardly swinging backsection having its lowerextremities pivoted tosaid base, `a forwardly swinging back sectionhaving its upper extremities pivoted tosaid. irst men# tioned section,the said sections being arranged to swing rearwardly to-form anadditional seat and to be unfolded to form a bed,

and a forwardly projecting support rigidly connected with the lowerextremity of said forwardly Aswingingbac'k section arranged to act as anarm section betwe'en'said back and additional seat and asi-a prop2 forsaid bed.

5. A convertible chaircomprising a base having a foldable back pivotedthereto ,and arranged to be swung rearwardly in to a horizonta positionand unfolded to form a bed, and horizontally swinging. side armsmountedl on said base arranged to support said back in anupriglhtposition and to swing inwardly to form a ead for said bed.

In witness whereof I have hereunto set my handthis 4th day ofJ'anuary,A. D. 1908.
